Hi Joel
Thanks for you kind words on the cockpits. Eduard have done fantastic job on the standard (profiPACK) kit, so I'm really looking forward to tackling the Brassin version in due course.

I had reasonable luck with the filling:
I'm glad I went with the Vallejo filler, because it was a typical case of consulting a reference photo too late!

I'd used what seemed to me to be logical guesswork in filling some panels and leaving others open - only to have it totally contradicted by a shot of Mustang on the production line.

So, I opened up some panel lines that I'd filled, and filled some that I'd assumed should be clear. Thank heavens I didn't go straight for the CA+Talc!

I'm still not sure about the panels with the fasteners on the leading edges, so I may well open those up too.
Meanwhile... I've started tinkering with the undercarriage. It doesn't include brake-lines, so they're something I'll definitely look to adding. But, as a first really simple tweak, it's worth drilling out the solid tabs on the gear legs to represent the towing points:
More soon.
Take care everyone and keep safe
